1992- 1996 Silverado Hood Will Not Open

To open the hood of a 2004 Chrysler Pacifica with a dead battery, try these steps:
Find hood release lever: Usually located on left side of driver's footwell near the hood release cable.
Jump-start battery: Connect battery to another car's battery if it's completely dead. This will provide enough power to release the hood latch.
Use manual release: If jump-starting is not possible, consult owner's manual for manual release location.
Get help: If unsuccessful, call for help from a tow truck or mechanic.
Caution: Make sure the car is in park, emergency brake is engaged and engine is off before opening the hood.

Jumper 12 volt battery power to the inside fuse box is the best method here.

I would try crawling under vehicle and hooking red jumper cable to big copper stud on starter where the battery cable hooks up, hook the black cable to the frame and hook the other ends up to another vehicle like you were jumping it off. And it should feed the battery with enough power to get the doors open to get the hood up. Good Luck

unfortunately there is little more than just forcing it open. this will cause damage and the hood latch may need to be replaced. but it will get you open

Fantom power drain. Make sure nothing is plugged into the lighter Make sure no lights are on like under hood or visor mirrors Turn off radio and make sure no cd/tape is in
Ignition switch might be bad A good battery should last 2 weeks just sitting. A old battery will go dead overnight especially if cold

it sits on the pass. front corner of the engine compartment, has a large black tube clamped to it, has 4 screws that hold the square cover on..

The key will open driver door of the truck manually, just like in the old days before electric locks.

Reply what you find and I can help further.

Sorry to hear that at Christmas Day.I'm sorry brother , but the only thing to do is call the locksmith .Because if you try to open the hood any other way , you may dent your truck.
